Raphael Isemann 36162014c4 [lldb][NFC] Remove dead code that is supposed to handle invalid command options
Summary:
We currently have a bunch of code that is supposed to handle invalid command options, but
all this code is unreachable because invalid options are already handled in `Options::Parse`.
The only way we can reach this code is when we declare but then not implement an option
(which will be made impossible with D65386, which is also when we can completely remove
the `default` cases).

This patch replaces all this code with `llvm_unreachable` to make clear this is dead code
that can't be reached.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Jonas Devlieghere ceff6644bb Remove header grouping comments.
This patch removes the comments grouping header includes. They were
added after running IWYU over the LLDB codebase. However they add little
value, are often outdates and burdensome to maintain.

Pavel Labath 2272c4811f Use llvm::VersionTuple instead of manual version marshalling
Summary:
This has multiple advantages:
- we need only one function argument/instance variable instead of three
- no need to default initialize variables
- no custom parsing code
- VersionTuple has comparison operators, which makes version comparisons much
  simpler

Zachary Turner 97206d5727 Rename Error -> Status.
This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.

A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error".  Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around.  Hopefully nothing too
serious.

Zachary Turner 1f0f5b5b9e Convert option tables to ArrayRefs.
This change is very mechanical.  All it does is change the
signature of `Options::GetDefinitions()` and `OptionGroup::
GetDefinitions()` to return an `ArrayRef<OptionDefinition>`
instead of a `const OptionDefinition *`.  In the case of the
former, it deletes the sentinel entry from every table, and
in the case of the latter, it removes the `GetNumDefinitions()`
method from the interface.  These are no longer necessary as
`ArrayRef` carries its own length.

In the former case, iteration was done by using a sentinel
entry, so there was no knowledge of length.  Because of this
the individual option tables were allowed to be defined below
the corresponding class (after all, only a pointer was needed).
Now, however, the length must be known at compile time to
construct the `ArrayRef`, and as a result it is necessary to
move every option table before its corresponding class.  This
results in this CL looking very big, but in terms of substance
there is not much here.

Zachary Turner 6fa7681bb6 Convert many functions to use StringRefs.
Where possible, remove the const char* version.  To keep the
risk and impact here minimal, I've only done the simplest
functions.

In the process, I found a few opportunities for adding some
unit tests, so I added those as well.

Tested on Windows, Linux, and OSX.

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

Todd Fiala e1cfbc7942 Decoupled Options from CommandInterpreter.
Options used to store a reference to the CommandInterpreter instance
in the base Options class.  This made it impossible to parse options
independent of a CommandInterpreter.

This change removes the reference from the base class.  Instead, it
modifies the options-parsing-related methods to take an
ExecutionContext pointer, which the options may inspect if they need
to do so.

Zachary Turner 1124045ac7 Don't #include "lldb-python.h" from anywhere.
Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.

None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

Greg Clayton ccd2a6d958 Changes in 226712 needed some fixing as a platform is almost always selected and even if platform options are specified when doing a "target create" they would get ignored if a platform was already selected.
The change was made so we could re-use a platform if one was already created instead of creating a new one, but it would fail in the above case. To fix this, if we have a selected platform, we verify that the platform matches the current platform before we try to re-use it. We do this by asking the OptionGroupPlatform if the platform matches. If so, it returns true and we don't create a new platform, else we do.

- change all callbacks that create platforms to returns shared pointers
- fix TestImageListMultiArchitecture.py to restore the "host" platform by running "platform select host"
- Add a new "PlatformSP Platform::Find(const ConstString &name)" method to get a cached platform
- cache platforms that are created and re-use them instead of always creating a new one

Zachary Turner de963e9a09 Adds the notion of an OptionValidator.
The purpose of the OptionValidator is to determine, based on some
arbitrary set of conditions, whether or not a command option is
valid for a given debugger state.  An example of this might be
to selectively disable or enable certain command options that
don't apply to a particular platform.

This patch contains no functional change, and does not actually
make use of an OptionValidator for any purpose yet.  A follow-up
patch will begin to add the logic and users of OptionValidator.

<rdar://problem/13594769>

Main changes in this patch include:
- cleanup plug-in interface and use ConstStrings for plug-in names
- Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp
- Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging

The plug-in interface changes:

Modified the lldb_private::PluginInterface class that all plug-ins inherit from:

Changed:

virtual const char * GetPluginName() = 0;

To: 

virtual ConstString GetPluginName() = 0;

Removed:

virtual const char * GetShortPluginName() = 0;

- Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. 
- Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc.

Greg Clayton 3bcdfc0ec1 <rdar://problem/12798131>
Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite.

This fix does the following:
- make sure all short options are treated as "int"
- make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired
- fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates
- fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value

Greg Clayton 1c5f186f30 Added new options to "target create" and "target modules add".
For "target create" you can now specify "--no-dependents" to not track down and add all dependent shared libraries. This can be handy when doing manual symbolication. Also added the "--symfile" or "-s" for short so you can specify a module and a stand alone debug info file:

(lldb) target create --symfile /tmp/a.dSYM /usr/bin/a

Added the "--symfile" option to the "target modules add" for the same reason. These all help with manualy symbolication and expose functionality that was previously only available through the public API layer.

lldb_private::Error objects the rules are:
- short strings that don't start with a capitol letter unless the name is a

- no trailing newline character
- should be one line if possible

Greg Clayton cac9c5f971 Added to the public API to allow symbolication:
- New SBSection objects that are object file sections which can be accessed
  through the SBModule classes. You can get the number of sections, get a 
  section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
  us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object

This should get us a lot closer to being able to symbolicate using LLDB through
the public API.

Removed the "image" command and moved it to "target modules". Added an alias

Added some new target commands to be able to add and load modules to a target:
(lldb) target modules add <path>
(lldb) target modules load [--file <path>] [--slide <offset>] [<sect-name> <sect-load-addr> ...]

So you can load individual sections without running a target:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib __TEXT 0x7fccc80000 __DATA 0x1234000000

Or you can rigidly slide an entire shared library:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib --slid 0x7fccc80000

This should improve bare board debugging when symbol files need to be slid around manually.

Greg Clayton 7260f6206f Centralized a lot of the status information for processes,
threads, and stack frame down in the lldb_private::Process,
lldb_private::Thread, lldb_private::StackFrameList and the 
lldb_private::StackFrame classes. We had some command line
commands that had duplicate versions of the process status
output ("thread list" and "process status" for example). 

Removed the "file" command and placed it where it should
have been: "target create". Made an alias for "file" to
"target create" so we stay compatible with GDB commands.

We can now have multple usable targets in lldb at the
same time. This is nice for comparing two runs of a program
or debugging more than one binary at the same time. The
new command is "target select <target-idx>" and also to see
a list of the current targets you can use the new "target list"
command. The flow in a debug session can be:

(lldb) target create /path/to/exe/a.out
(lldb) breakpoint set --name main
(lldb) run
... hit breakpoint
(lldb) target create /bin/ls
(lldb) run /tmp
Process 36001 exited with status = 0 (0x00000000) 
(lldb) target list
Current targets:
  target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped )
* target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited )
(lldb) target select 0
Current targets:
* target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped )
  target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited )
(lldb) bt
* thread #1: tid = 0x2d03, 0x0000000100000b9a a.out`main + 42 at main.c:16, stop reason = breakpoint 1.1
  frame #0: 0x0000000100000b9a a.out`main + 42 at main.c:16
  frame #1: 0x0000000100000b64 a.out`start + 52

Above we created a target for "a.out" and ran and hit a
breakpoint at "main". Then we created a new target for /bin/ls
and ran it. Then we listed the targest and selected our original
"a.out" program, so we showed two concurent debug sessions
going on at the same time.
